Image of the Week: Breast cancer indicator protein

This image shows a protein called Elf5, which is necessary for lactation in mammals. Findings (subscription required) published in this month’s issue of Nature Cell Biology suggests that the protein could play a role in inhibiting the cellular transition that is an early indicator of breast cancer. In a recent University at Buffalo release, researchers explained how the discovery could open up new options in treating and diagnosing breast cancer, and potentially other cancers.
